There were conflicting reports initially on the ages of the victims, but the Associated Press quotes fire department Maj. Tammy McKinney as saying the dead were four children ages 2 to 8 and one woman.

One other adult was hospitalized in critical condition, McKinney said.

"When we got on scene, we had reports that there were children inside," McKinney said, according to the AP. "The fire was so intense that we could not make entry and had to knock the fire down before we could make entry. That's when we found the bodies."

Battalion Chief Randy Cornelius said the interior of the home, about a mile east of Lake Hefner in northwest Oklahoma City, appeared completely "gutted" by the fire, the Associated Press reported.

NewsOK reporter Robert Medley said fire investigators were still looking into the cause of the fire but have not reported finding anything suspicious.

NewsOK quoted a neighbor, Toni Wyatt, as saying she rushed over to the blaze after smelling smoke and hearing three loud pops at 6:30 a.m. CT.

"I heard a guy yelling, 'Help! Help!' I went over to see what was going on and helped pull the guy out of the house," Wyatt told NewsOK.
